The paper introduces a new aeration technology for stationary tanks with water mass. It is a passive aeration based on the principle of air diffusion, or more precisely oxygen diffusion into water. It uses the principles of Henry's law to increase the effect of diffusion. The basic element of this technology is a superhydrophobic or preferably an ultrahydrophobic surface. The basic characteristic, experimentally verified within this work, is the ability of the hydrophobic surface to bind the gas molecules. This makes the surface simultaneously aerophilic. The work includes the equipment design that utilizes this property. It is a cylinder provided with a double base. The first base closes the cylinder in conventional manner; the second base is formed by a porous membrane, which is fed from the bottom side with the gas (air, oxygen). Due to the aerophilic effect, a thin layer of ai.. Read More»DOI: 10.4172/0976-4860.1000147
